Description

Technical Field

[0001] The utility model relates to the technical field of automatic verification, in particular to a batch automatic function verification tooling for an AC orderly charging pile. Background Art

[0002] In the prior art, the verification of new energy charging piles is generally carried out manually, which has many disadvantages: 1. It is easy to connect the wrong wires when manually connecting each charging pile. There is a 220V high-voltage electricity and large current test environment of 5A, 10A, 20A to 30A. If the wires are connected wrongly manually, electric shock safety accidents are likely to occur. Manual multi-gear switching is inefficient and prone to mistakes and failures, and there is no 220V high-voltage electricity safety protection mechanism. 2. Manually set the triple combination of a single charging gun of a charging pile with a debugging software tool to write networking information. Manually copying and pasting the triple information leads to network communication failures and misalignment, and cannot perform automatic continuous testing. 3. Manually controlling 1 wheeled calibration meter and verification meter is likely to result in the mixing of defective and non-defective products during the verification meter test, and cannot perform continuous testing of multiple units in 1 round. It is difficult to control the test efficiency and quality yield. 4. There is no systematic and accurate judgment of parameter values for the test results. It is necessary to manually input program instruction codes in the CRT software to calibrate the 5A, 10A, 20A, and 30A currents of AC charging products, and rely on manual viewing of numerical values for discrimination and judgment, resulting in the quality risk of the verification meter results being invalid. 5. The test data of the test results are stored and traced manually on paper, which has loopholes.

[0003] To meet the detection requirements of product safety protection, reliable quality, and high efficiency, low cost for the single-pile controller of new energy charging piles, either a dedicated large-scale test environment site needs to be configured, and customized non-standard and expensive special new energy power verification meter platforms and equipment are required. Their cost performance is relatively too high for small and micro enterprises, and the expected effects and high non-standard supporting after-sales services cannot be achieved.
